Question about Refrigerators
Is the compressor running? Is the coils near the compressor clean and is the fan that blows on the coils running? Does it get cold at all or is it room temp? One thing to do is to turn it on after leaving it unplugged for and hour. First access the compressor and make sure you can feel the copper lines coming out of it. Some have 4 plus a service pigtail. On the ones with 4 will have two lines the same size that circulate oil for cooling the compressor running to a small set of coils. Pay attention to the larger and smaller lines and notice what temperature they feel like before you plug it back in. Once it is plugged in and if the compressor is running less than a minute the small line should get hot, up to 140 degrees F. Check it soon as after a few minutes it can burn you...The largest of the lines is the low side or suction side and it should be very noticeably cooler than room temp and continue to get colder the longer it has been running. If both these things happen, the charge should be adequate, and the compressor is working. I would then check to see if air is circulating in the unit..Are all the fans running when the unit is on? Most common is for the defrost circuit to fail causing the unit to build up ice behind the liner blocking air flow. Unplugging the unit and leaving the doors open over night will let it thaw. Put several towels around the unit incase this is the problem as there will probably have more water come out than the small pan under neath the unit can handle. Once all the water stops dripping out, plug it back in and see if it works correctly. If so it will probably freeze up again and need to be defrosted again. If so the defrost circuit has failed....either the thermostat in that circuit, the heater coils or the defrost timer switch. Switch very common, coils next and the high temp sensor last.... let me know what you find...
